Chris,
=0A
  Having just received my = TO4E-50 turbo from Turbonetics made me think to
=0A
ask if y= ou were developing boost and what rpms were involved as you noticed=0A
your oil pressure dropping ?..........Hopefully lack of oil= pressure has caused
=0A
no damages to your turbo bearings b= ut you probably should check yours to
=0A
see if the comp/turbine= wheel is still turning freely..........If there is any question
=0Ait probably should be inspected..........I would not run the engine with= the turbo
=0A
attached even after correcting your oil pressure pr= oblem without assuring that 
=0A
it is healthy if it were me= ............FWIW

The engine is off the engin= e, prop and all in one big swoop.  It actually was pretty easy as, sin= ce I have labored over it so often and finally h= ave it rigged as I want it and not just sloppy proof of concept stuff, the = process was methodical and only took an hour or two.  I hope to pop th= e pan after work tomorrow.

Very little oil pressure would be left inside the cr= ank while cold. Should that gizmo fail, oil pressure would get worse as the= temperature goes up. I assume that you replaced the stock piece with a sol= id nonfunctioning

piece to avoid this kind of failure.
